6. Reduced Flow Force

By changing the structure in the control valve, the hydraulic oil flow has been reviewed and theresistance (flow force) was reduced to greatly improve fine operability and provide a linear responsethat better approximates human sensation.

This is when it is effective!

For hanging work, precision work (positioning), etc., the cylinder movement is linked linearly to theoperation lever movement.

For fine operation, such as pin hole position alignment when replacing the bucket

For fine work such as leveling and grading

Even for work that requires speed, such as continuous piling, even for compound operations, theoperation feel is smooth and stress-free.This is one example of a swing line.The hydraulic oil flow has been changed to have the same direction as the spool.The resistance (flow force) has been reduced and smooth movement attained.The same type of improvements has been made at many locations to improve the operability.

1 Motor 5 Same direction as spool movement

2 Path within valve is changed. 6 High flow enters the spool.

3 Fluid force; High 7 Low flow within spool

4 Fluid force; Low 8 Direction in which the spool is moved

7. Straight Travel Valve

Improved operability during simultaneous upper side and travel operationEven when the lever is operated during traveling, the travel speed is smoothly reduced according tothe degree of lever operation.

This is when it is effective!

In traveling on steep slopes for construction in mountainous areas (afforestation-related civilworks, construction of new forest roads, etc.), the operator would have to simultaneously performtraveling and arm operation.When the arm is moved, the ratio of hydraulic oil flowing to the travel motor is reduced. Thestraight travel valve is adjusted according to upper lever operation to enable shock-free speedreduction and ensure straight travel stability.

Model 5 circuit

This is an example of simultaneous boom-up operation and travel.Through upper (boom-up) lever operation, the pilot pressure oil from the remote control valve flowsin the control valve Pa4 port and the boom spool is switched. At the same time, the pilot pressure oil

split internally is fed to the straight travel valve via the straight travel signal (left) and the straighttravel spool is switched.The amount of switching of the straight travel spool varies with the upper (boom-up) pilot pressure.This prevents any sharp drop in travel speed.

8. Heat Circuit

Faster warm upThe pilot line warms up more quickly due to a change in oil flow so that the heated oil returnsthrough the remote control valve.

When heat circuit is operated (for arm and boom single-side operation), warm-up speed increase (cushion valve).

Model 3B Model 5

* There is no soft/hard switch.

With the circuit change, the metering position is optimized,which increases the warm-up oil flow and shortens warm-up time.

Model 3B circuit

Almost all the heated oil was dropped into the tank and it was difficult to heat the pilot line.

Model 5 circuit

In neutral, since an orifice has been put at the reverse notch spool, almost all the heated oil issent to the pilot line.
